Why Kubbly:
There’s no better feeling than when you walk into your local coffee shop or restaurant and the team starts prepping your “usual” before you’ve even reached the register. The feeling of being known. Kubbly is building technology that will give any consumer business, no matter how big or small, the power to deliver this kind of personal, high-touch service to each customer.
With our platform, a hotel can suggest the perfect hotel room to a loyal customer before they even start planning their next vacation. Mom can text her favorite restaurant for “the usual” and have that club sandwich on her plate minutes later.
Behind that simple “the usual” moment is a deep technical challenge, building real-time systems that understand intent, timing, and personal context at scale.
Currently, most business messages feel like spam. At Kubbly, we are changing that. We are enabling actual conversations. Individuals get individual experiences, and businesses get loyal customers who feel seen, not sold to.
We need builders who can help us bring “the usual” to millions. You’ll join at the perfect moment — early enough to shape what we build next, proven enough to know it’s working, with the chance to solve real problems and influence decisions you’d never touch at a larger company.
Reasons to join us:
The founders actually built similar stuff before. Piyush and Giorgos have previous experience building similar startups, licensing technologies to Fortune 1000 companies, and 10+ years experience building ML and recommendation systems at Amazon and Goldman Sachs.
We're backed by Bek Ventures (formerly Earlybird Digital East). They backed UiPath and Payhawk before they were cool. They're founder friendly, provide immense value to their portfolio companies and don't micromanage.
You'll own the full pipeline, not tickets. Your code won't go through 5 layers of review. You'll have major role in deciding what to be built, how something should work, build it, ship it, and see customers use it.
We actually talk about technical problems. Weekly tech talks, paper discussions, post-mortems on interesting bugs. The founders are engineers first - they'll geek out with you about implementation details.
Competitive comp + equity.
About the role:
At Kubbly, we believe AI will really change the way customer engagement works. We believe getting to know your customer is a right that not only large businesses or third-party marketplaces can afford. Everyone from medium- to small businesses to solopreneurs should be able to get to know their customers and create engaging ways to interact with them. As Founding ML/AI Engineer you’ll be responsible for building the agentic systems and tools that would enable businesses to drive customer engagement and enable two-way conversation.
You will work alongside the founding team to drive the product roadmap, develop new features and scale the platform. You will be product- and customer-obsessed. This is a great opportunity to play a key role in the design and development of product directly used by businesses to drive customer engagement.
Our philosophy: We operate on high conviction, low ego. We value passionate, data-driven ideas. We debate vigorously to find the best solution, but then align as a team to execute.
We are mostly in-office from our awesome HQ in Williamsburg - 4 days per week. That’s not because we’re obsessed with processes but because we’ve seen it in our previous roles that live collaboration fosters cross-pollination and team bonding that a fully remote team cannot experience.
What You’ll Do:
This is a founding role - You get to collaborate closely with the founders to help shape the vision and product roadmap.
Research, architect, prototype and deploy LLM-based solutions that would expand our customer engagement engine or customer two-way communication product.
Stay on top of the latest developments in AI and dev tooling and find tangible ways to introduce them to our daily work.
Collaborate on building internal tools, datasets, and evaluation pipelines.
Run A/B tests and user experiments to validate hypotheses.
Partner with founders and fellow engineers to architect and build scalable AI solutions.
Create and maintain clear documentation while adhering to code best practices (git, PRs).
Mentor and provide guidance to the team, helping them grow their expertise in AI.
Who You Are
Soft Skills
Stubbornness on the vision, flexibility on the details (borrowed by Jeff Bezos ). This means that:
You are flexible and curious to learn about new things constantly.
You are perfectly fine to bury the hatchet for efforts that don’t lead to PMF and view this is as a learning opportunity.
Customer Obsession: we’re small and what we build is driven only by our desire to achieve PMF. This means we listen to our customers’ pains and work backwards to create awesome solutions.
Desire to work (mostly in person), next to CTO, CEO and being involved with engineering decisions.

About the Company
Messaging app inbox is becoming the most valuable smartphone real estate. But most businesses are unable to capitalize on that real estate meaningfully without sounding like spam. We help businesses build better, more human customer experiences, starting with AI agents that engage customers with timely, personalized messages on SMS, WhatsApp, RCS, and iMessage and holding 2-way conversations that drive repeat purchases. All without writing a single line of code.
